Death Row (2006)

About the worst aspect of Death Row is its cast; not because of the acting but because with half the characters being criminals, ones shown to be without qualms about killing, there's not much reason to invest in these guys.

Sure, Steven Monroe made similar characters somewhat sympathetic in Sasquatch Mountain, but Monroe's movies usually put more effort into the characters than most horror movie crews do today...

Anyways, we see these people's deaths coming from miles away. Fortunately, the writers managed to think of interesting methods of offing people, and there is occasional humor thrown in, keeping the inevitable entertaining.

Most importantly, it is fun horror. While watching people get offed one by one, without any atmosphere or investment in the characters, keeping it entertaining is important.
